The Springboks remain the top-ranked team in the world on 93.96 rating points following their 17-10 Rugby Championship win over Argentina in Buenos Aires, heading into the four-Test Greatest Rivalry Series against New Zealand with a 1.68-point buffer over the All Blacks (92.28).

Tries from Cameron Hanekom and Edwill van der Merwe proved the difference after the teams were locked at 10-all at half-time. The result earned South Africa no additional rating points, with the same applying to Argentina, who stay seventh on 83.13.

Australia climbed to eighth on 82.09 — a gain of 0.48 points — after Les Kiss's first match in charge ended in a 35-32 win over Japan in Osaka. The margin was enough to narrow the gap on Argentina but not to displace them. Japan dropped two places to 12th as a direct consequence, their fall lifting Wales back into the top 10 for the first time since July 2024. Wales sit 10th on 76.38, with Italy 11th on 76.30.
